Remove coherent memory from the BL memory maps
This patch extends the build option `USE_COHERENT_MEMORY` to conditionally remove coherent memory from the memory maps of all boot loader stages. The patch also adds necessary documentation for coherent memory removal in firmware-design, porting and user guides. Fixes ARM-Software/tf-issues#106 Change-Id: I260e8768c6a5c2efc402f5804a80657d8ce38773
